Answer:
well, during reflection
angle of incident is equal to angle of reflection so if angles of incident is 23° , then angle of reflection is also equal to 23° .
so the total angle between the reflected and incident ray will be equal to angle of incidence plus angle of reflection
i.e. angle i + angle r = 23° + 23° = 46°
hence the required angle is 46°
<em>i</em><em> </em><em>hope</em><em> </em><em>it</em><em> </em><em>helped</em><em> </em><em>.</em>
a = dv/t = (330-x)/1.5 =50
x= 330-75 = 255 m/s
Intial velocity 255 m/s
Yes, because cell phones use scientific structure to build.
The normal force of the force given is calculated through the equation,
Fn = F(sin θ)
where Fn is the normal force, F is the force, and θ is the angle.
Fn = (25 N)(sin 60°) = 21.65 N
The x-component of the force applied is,
Fx = (25 N)(cos 60°) = 12.5 N
The value of the coefficient of static friction is calculated through the equation,
F = μFn
μ = Fx / Fn = 12.5 N / 21.65 N = 0.577
